This report is one of three technical reports of Tracking California's Trash – a Proposition 84 Storm Water Grant Program project funded in large part by the State Water Board. BASMAA and its project partners – 5 Gyres, City of Fremont, City of Oakland, City of San Jose, San Mateo Countywide Water Pollution Prevention Program, and Santa Clara Valley Urban Runoff Pollution Prevention Program provided the match funds.
The primary objectives of the project were to:
This report presents an evaluation of effectiveness and cost of two best management practices for trash – street sweeping and curb inlet screens.
Monitoring was conducted at seven study areas located in the cities of Fremont, Oakland, and San Jose, California. Monitoring activities included the removal of trash from streets, sidewalks, and drain inlets in three of the seven study areas (i.e., quantitative study areas) immediately before and after street sweeping events. The collected trash was quantitatively characterized in terms of weight, volume, and item counts. Quantification events were supplemented with qualitative On-land Visual Trash Assessments (OVTAs), which were conducted at all seven sites before, after and between street sweeping and rainfall events.
